Bloodworm (Chironomid Larva)

Freshwater sediments, including lakes, rivers, ponds, and slow-moving streams. Some species are found in brackish or even marine environments.

Detritivores; they consume organic debris, algae, and microscopic organisms found in the sediment.

They are the aquatic larval stage of non-biting midges. They produce hemoglobin to absorb oxygen in low-oxygen environments, which gives them their red color. They typically live in silk-lined tubes within the substrate.

Benefits: They are a crucial component of the aquatic food web, serving as a primary food source for fish and waterfowl. They also help decompose organic matter. Risks: Non-biting midges can become nuisances in large swarms, but they do not bite or pose a direct health risk to humans.
